摘要: 应用Design Expert7.0软件技术,采用响应曲面法设计、分析,研究提取液pH值、提取温度、提取时间及盐析温度四个因素中的两个因素交互作用对香蕉皮果胶提取得率的影响。结果表明,这四个因素中任两个因素的交互作用都会对果胶提取得率产生影响。尤以提取温度和提取时间交互作用、提取温度和盐析温度交互作用、提取时间和盐析温度交互作用对果胶提取得率影响最为明显。

Abstract: By using the software Design Expert 7.0 and Response Surface Method(RSM),the interaction between any two factors and its effect on extraction ratio of pectin from banana peel were studied from four factors(pH value,extraction temperature,extraction time and salting out time).The results showed that the interaction between any two factors affects the extraction ratio of pectin.There are significant effects on the extraction ratio of pectin especially in the interaction between extraction temperature and extraction time,the interaction between extraction temperature and salting out temperature,and the interaction between extraction time and salting out temperature.

Key words: pectin extraction, affecting factor, interaction
